Overview

[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
Gynecomastia must be differentiated from pseudo gynecomastia, breast cancer, lipoma, mastitis, dermoid cyst or pectoralis major hypertrophy.

[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
[Disease name] must be differentiated from [[differential dx1], [differential dx2], and [differential dx3].

As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].

Differential Diagnosis	Similar Features	Differentiating Features

Gynecomastia	On [physical exam; history; diagnostic test; imaging], [Differential 1] {has; demonstrates} [feature 1], [feature 2], [feature 3] also observed in [disease name].	Round discrete mass felt under areola and usually bilateral.
Pseudogynecomastia	On [physical exam; history; diagnostic test; imaging], [Differential 1] {has; demonstrates} [feature 1], [feature 2], [feature 3] also observed in [disease name].	Increased adipose rather than glandular tissue on examination.
Lipoma	On [physical exam; history; diagnostic test; imaging], [Differential 1] {has; demonstrates} [feature 1], [feature 2], [feature 3] also observed in [disease name].	Asymmetric breast enlargement.
Breast cancer	On [physical exam; history; diagnostic test; imaging], [Differential 1] {has; demonstrates} [feature 1], [feature 2], [feature 3] also observed in [disease name].	Nipple discharge, Axillary lymphadenopathy, usually nonpainful mass.
Sebaceous cyst	On [physical exam; history; diagnostic test; imaging], [Differential 1] {has; demonstrates} [feature 1], [feature 2], [feature 3] also observed in [disease name].	Asymmetric enlargement and swelling feels closer to skin.
Mastitis	On [physical exam; history; diagnostic test; imaging], [Differential 1] {has; demonstrates} [feature 1], [feature 2], [feature 3] also observed in [disease name].	Systemic s/s of infection.
